    The impact of import in inflation in Namibia
    (ID publications, 2017) Sheefeni, Johannes P.S
    This study examined the impact of imports on inflation in Namibia using quarterly data from the period 1991Q1 to 2013Q4. The model estimated used imports as a dependent variable, while gross domestic product, money supply (M2), lending rate, and exchange rate as the explanatory variables. An error correction modelling approach was applied on the double log functional form in order to investigate the significance and effect of explanatory variables to inflation in Namibia. The results for the unit root test showed that all the variables were stationary in first difference. The residual based test to cointegration revealed that there is cointegration among the variables. The error correction model showed that imports have a positive effect on inflation in the long run while in the short run the effect is insignificant.

    Testing for the Fisher hypothesis in Namibia
    (Journal of Emerging Issues in Economics, Finance and Banking, 2013-07) Sheefeni, Johannes P.S
    This paper analyses the relationship between interest rate and inflation in Namibia. The objective is to test whether the Fisher hypothesis holds in the long run. Using monthly data for the period 1992:01 – 2011:12, the paper employed time series techniques, namely, unit root tests and cointegration test. The unit root test reveales that the series are non stationary. The cointegration test shows that there is no cointegration among the variables. Hence, the long run relationship between inflation and interest rate is non existent. The study rejects the Fisher hypothesis in the Namibian context. In the absence of cointegration the study could not proceed with Granger causality test.
